He became Director of the Center for Experimental Computer Science.

Around 1980 he worked on the LOCUS distributed operating system, an early implementation of the single-system image idea.

Between April 1981 and June 1983 Popek served on the DARPA "steering committee" for BSD UNIX formed by Duane Adams of DARPA to guide the design work leading to 4.2BSD. Other members of the committee were Bob Fabry, Bill Joy and Sam Leffler from UCB, Alan Nemeth and Rob Gurwitz from BBN, Dennis Ritchie from Bell Labs, Keith Lantz from Stanford, Rick Rashid from Carnegie-Mellon, Bert Halstead from MIT and Dan Lynch from ISI.
